MD201706 is out and features code from T.M.R, accompanied by Odie's cover of the completion tune from Brian The Lion. This release is a bit unusual, since it requires either a Turbo Chameleon (set to 6MHz or faster) or SuperCPU epansion to run. When pressed for comment as to why the extra hardware was needed, T.M.R responded with "just because".

It's the end of May 2017 so just about time for the release of MD201705 - a reworking of a classic effect with a bit more colour than the last time we tried it! Once more, the bits were crammed together by T.M.R, with the music being a cover of the Protracker module "Atominus" by Maza.

The Monthly Demo instalment for April 2017 is, unsurprisingly, called MD201704 but at least the platform it runs is unusual; this is a 40 column C128 demo full of colourful raster splits in the upper and lower borders. Everything this time was handled by T.M.R including the music, an old cover of the Protracker module "Dozey" by Jozz.

How about a new graphical outing for the Caped Crusader on the C64? The latest instalment of our Monthly Demo series MD201703 - The Bat-Tro from T.M.R (bat code and bat graphics) and aNdy (bat music) can arrange that for you!

There's a new demo in town, it's name is MD201702 and there's music from Odie accompanying the FLI-based colour effects (not too far removed from those of MD201509 but with a few extra tricks up their sleeves) from T.M.R.
